The thin rib 5 and the loudspeaker cover plate 2 form a certain space, thereby constituting a cavity. On the one hand, the cavity provides a buffer area for the sound wave propagation inside the loudspeaker body 1, which helps to optimize the acoustic performance and makes the sound more uniform and stable during propagation, thereby improving the sound quality performance of the loudspeaker. On the other hand, the existence of the cavity can also play a certain role in heat insulation and shock absorption, reducing the influence of the external environment on the internal structure of the loudspeaker, and further prolonging the service life of the loudspeaker.

[0044] Further, referring to Figure 4 , the buckle groove 211 comprises a first groove 2111 and a second groove 2112, the first groove 2111 is arranged along the axial direction of the loudspeaker cover plate 2, and the second groove 2112 is connected to the end of the first groove 2111 and is arranged along the circumferential direction of the loudspeaker cover plate 2; after the buckle block 4111 enters the first groove 2111, the sound-producing body 3 is rotated, and the buckle block 4111 is suitable for entering the second groove 2112, so that the loudspeaker body 1 and the sound-producing body 3 are buckled and connected.

[0045] In this embodiment, the first groove 2111 extends along the axial direction of the loudspeaker cover plate 2, providing a straight path for the initial entry of the buckle block 4111; and the second groove 2112 starts from the end of the first groove 2111 and expands along the circumferential direction of the loudspeaker cover plate 2, forming a complete buckle groove 211.

[0046] Specifically, during the installation process, the buckle block 4111 first enters the buckle slot 211 along the axial path of the first slot 2111. Subsequently, by rotating the sound emitting body 3, the buckle block 4111 moves along the circumferential path of the second slot 2112, and the buckle block 4111 can smoothly transition from the first slot 2111 to the second slot 2112, and finally achieve the buckle connection between the loudspeaker body 1 and the sound emitting body 3. Among them, the first slot 2111 provides a clear entry direction for the buckle block 4111, ensuring the accuracy of the installation; while the second slot 2112 provides a fixed point for the buckle block 4111 through the surrounding structure, making the connection between the loudspeaker body 1 and the sound emitting body 3 more secure, and the reliability and durability better.

[0047] Preferably, the buckle slot 211 further comprises a pair of first guide walls 2113 arranged on both sides of the slot opening of the first slot 2111 and guiding the connection between the top surface of the loudspeaker cover plate 2 and the side slot wall of the first slot 2111, and the buckle block 4111 is adapted to enter the first slot 2111 along the first guide wall 2113.
